Message-Id: <1344115993-6363-1-git-send-email-jan.ariyasu@hp.com>

Cc: Jan Ariyasu <jan.ariyasu@...com>
Subject: [PATCH 06/13] SCTP: turn on namespace awareness for the state-machine functions.
In particular, turn on netns-specific control sockets in the
namespaces and set up the groundwork to use per-namespace sysfs
parameters in these functions.
